STEAM: LOOOMOEHVE:

This invention relates to improvements in steam locomotives and has particularreference to articulated locoinoti with water. power driven gr boiler: unit: being; flexibly prising. a. boiler unit tanks, and two wheels, the said ves comand fuel cups of attached to and carried by the frameworks of the power driven groups The object of the of wheels. present invention is to effect improvements in the construction of locomotives to provide an articulating locomotive comprising a boiler unit carrying tanks and having acarrier frame provided with a bogie pivot beyond the boiler a power unit and driven group of driving wheels in which the power unit is provided with tanks arranged beyond center at each end a power the end of the boiler unit and connected to one of the pivot centers of of a locomotive constructed and arranged in the carrier frame while the other pivot center of the carrier frame is connected with a power driven group said power driven groups of vided of wheels and wheels is prowith an additional power driven flexibly pivoted thereto whereby the stability of the locomotive is materially increased formly distributed over the groups of wheels.

The driving sources piston engines or and theload is unipower driven may be reciprocating turbines or other steam motor or any combination thereof and may be simple or compound londensers may as desired. be provided at any part of the locomotive, in lieu of or in addition to water tanks and such condensers may be of any form or system. lVater tanks or fuel or any tanks, or condensers combination thereof may be pro vided on separate vehicles or tenders.

The locomotive may be provided with power generators, veuient part.

or of driving the locomotive of aturbine-dynaino generator driving electric motors on the axles of the driving wheels or turbo hydraulic transmission.

The power driven groups power driven units or both in with carrying or bogie number and position of the size number and The invention may be app of w heels or ay be provided wheels and such wheels as also position of driving or coupled wheels may be as desired.

tives designed for use in conjunction with rack rails, centre. railsand the like.

It will .be understood that the term power a fuel tank, and H indicates the fuel tank' or fuel. and water tank and K a condenser carried on the frame of the boiler unit A.

The power driven group of wheels or power driven units or both are provided with any number of additional power driven groups of wheels or additional power driven units or both, to give increased power to the locomotive from the boiler when called for as in going up an incline. Additional power driven groups of wheels E and F are flexibly connected by vertical pivots P to E and F at J and J the frameworks of the group E and unit F extending over and being sup ported upon the frameworks of the additional groups E and F as shown.

Auxiliary water or fuel tanks may vided as described.

hat I claim and ters Patent is be prodesire to secure by Let- 1. An articulatedlocomotive comprising a wheels, the power unit being provided with tanks arranged beyond the end of the boiler unit and connected to one of the pivot centers of the carrier frame while the other pivot center of the carrier frame is connected to the power driven group of wheels, said power driven group of wheels being; provided with an additional power driven group of wheels flexibly pivoted thereto.

2. An articulated. locomotive in accordance with claim 1, wherein the power unit is provided with an additional power driven group of wheels flexibly pivoted thereto.

3. An articulated locomotive comprising aboiler carrier frame, a power driven bogie at each end of said frame and each pi votally connected thereto, one end of said frame having an extended portion which extends over one of said bogies and a power driven bogie pivotallv connected to one of the first named bogies.

t. An articulated locomotive comprising a boiler carrier frame, a power driven bogic pivotally connected to each end of said carrier frame and a power driven bogie pivotall v connected to the outer end of each of the first named power driven boggles.

In witness whereof I atiix my signature.
